Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

Low cost composite materials are widely used in civil and structural engineering applications. This project uses EPON to plasticize a commonly used resin, epoxy resin to lower the cost of the composite and to find out the mechanical and thermal properties of the plasticized epoxy resin to see if it is suitable for the said applications. Three point bending tests were carried out to evaluate the...

A novel method based on selective laser sintering (SLS) process is proposed for the first time to prepare complex and high-performance carbon fibres/polyamide12/epoxy (CF/PA12/EP) ternary composites. The procedures are briefly described as follows: prepare polyamide12 (PA12) coated carbon fibre (CF) composite powder; build porous green parts by SLS; infiltrate the green parts with high-performa...

The use of Carbon Fiber–Reinforced Polymers (CFRP) has increased in number of industries i.e. aerospace, automobiles, marine, medical and sports due to their light weight and high strength-stiffness. However, their properties are greatly affected under extreme e environmental conditions i.e. high temperatures and moisture uptake. The paper reports an experimental study to determine the response...

introduction: the aim of this in vitro study was to evaluate the effect of mta-based sealer (mta fillapex), eugenol-based sealer (dorifill) and an epoxy resin sealer (ah plus) on the bond strength of fiber posts cemented with a self-etch adhesive. materials and methods: the root canals of 72 maxillary incisors were prepared using the step-back technique after removing/cutting off the crowns. th...

Rice straw waste is often a problem for farmers because of the lack utilization until finally, only burning done. The use rice composites aims to increase economy and maximize potential be more useful in industry. This research uses epoxy sikadur 52-id mixed hardener ratio (2:1) as matrix, fiber reinforcement, with length 3 cm. composition resin volume fraction 10% fiber: 90% resin, 20% 80% 30%...
